Can a metal bushing be used to reduce the size of threaded conduit?

Yes, a metal bushing can be used to reduce the size of threaded conduit. It serves as a transition fitting that allows for the connection of a larger conduit to a smaller threaded opening, ensuring a secure and tight fit. This is commonly done in electrical installations to accommodate different conduit sizes while maintaining proper wiring protection and support. Always ensure that the bushing is compatible with the conduit materials and sizes being used.
